Age and Origin of Siberian diamonds: a Re-Os isotope study of sulphide inclusions
Knowing the age of diamonds is critical to understanding their formation and likely distribution in the mantle. Re-Os isotope analyses of synergetic sulphide inclusions allows dating of indi ...

How do subduction zones initiate, develop and end: Imaging the Reversal of Subduction in the Solomon Islands (NERC grant NE/M00788X/1)
In this urgency proposal we will deploy seismometers for 1 year to record aftershocks from sequence of 4 major earthquakes with magnitudes between 7.1-7.6. These recordings and other recordi ...

The oxygen fugacity of core segregation and the redox evolution of the mantle: constraints from iron and chromium isotopes
This project is aimed at understanding what kind of conditions the Earth's core formed under and how this affected the amount of oxygen present in the rocky interior of the Earth. It uses ex ...
